1. Zoo Med Eco Earth Compressed Coconut Fiber Expandable Reptile Substrate — Best Overall

Zoo Med Eco Earth (3 Pack)


Made from the husks of coconuts, the Zoo Med Eco Earth Reptile Substrate is available in a form of compressed coconut fiber brick. Each compact brick can create seven to eight liters of loose substrate and is enough to cover a 10 to 15-gallon reptile tank with one-inch depth.

Key Features

  • Eco-friendly
  • Made from all-natural coconut husk
  • Sold as a compressed brick

Made from compressed coconut fiber, this bearded dragon substrate is ideal if you are looking to create a natural-looking tank setup. Coconut fibers naturally absorb and break down odor and waste products, thus ensuring your reptile’s tank is clean and fresh-smelling.

Since this bedding is compressed in a brick, you’ll need to place it in a bucket, add three to four liters of water, and leave it for 20 to 30 minutes to expand. Once the time is up, wring out any excess moisture and start setting up your beardie’s bedding.


  • Eco-friendly and can be safely recycled or composted into gardens or potted plants
  • Can be used damp for tropical species or dry for desert species, such are bearded dragons
  • Absorbs odors and waste, thus keeping the terrarium clean
  • One compressed brick expands to make seven to eight liters of bearded dragon substrate


  • Expanding the compressed brick and setting up the substrate takes time. If you are hard-pressed for time, the entire process can be inconvenient.
  • Since it’s a loose substrate, the coconut fiber can be messy and difficult to clean off of your floor and the area around your dragon’s tank.

The Zoo Med Eco Earth Compressed Reptile Substrate is the overall best bedding for bearded dragons and is great for natural-looking setups.


2. Zoo Med Premium Repti Bark Natural Fir Reptile Bedding – Runner Up

Key Features

  • Made from 100% natural fir bark
  • Hygroscopic
  • Reusable

Besides being hygroscopic, meaning that it absorbs moisture and then releases it, creating humidity, this substrate also conducts and evenly distributes heat. If that isn’t enough to impress you, fir bark is also highly absorbent and will pull nasty waste away from your beardie.

The fact that it’s reusable, super easy to clean, and great at odor control makes this substrate a great choice in my book. All you’ll need to do to keep your pet’s tank clean is soak the substrate in hot water every two to three months and voila! You have clean and fresh bedding for your bearded dragon.


  • Wasn’t heat-treated, so it has better moisture retention
  • The completely natural fir bark is easy to maintain and can be washed in hot water
  • Highly stimulating and supports digging and burrowing behavior for enrichment
  • Small pieces of bark interlock and prevent live food from burrowing or hiding in the substrate
  • Safe for tropical species and desert species


  • A few customers reported that there were mites in the bark, though this is extremely rare. To be on the safe side, you might want to consider checking and treating the bark for mites before using it to set up your beardie’s tank.

All in all, the Zoo Med Premium Repti Bark Natural Fir Reptile Bedding is a great choice if you are looking for a highly absorbent and easy to clean substrate for bearded dragons.

Things to Consider When Buying Bearded Dragon Substrate

Although there are many different types of substrates for bearded dragons, choosing the right one for your pet might be harder than it seems.

Finding the best substrate for bearded dragons comes down to personal preference, the size of your beardie, and the amount of time you have to keep their enclosure clean. Keeping that in mind, here are a few things you should consider when shopping for bearded dragon bedding:


As always, your pet’s safety comes first and should be your main concern when choosing a substrate. For the sake of your beardie’s health and wellbeing, make sure the substrate doesn’t contain any harmful dyes or toxic chemicals. Your best bet is to pick an all-natural and eco-friendly substrate that won’t irritate your pet in any way.

Additionally, to avoid impaction, choose substrates that are more finely ground with no large or hard pieces. Always keep your beardie’s food dish clean and free of stray pieces of loose substrate.

Reptile Mat or Loose Substrate

One of the first things you’ll have to do is decide whether to buy loose substrate or go with a reptile carpet. While loose bedding is closer to your pet’s natural habitat and will allow them to dig and burrow, it does sometimes pose a risk of impaction. Loose substrates aren’t recommended for juvenile bearded dragons, since they are more likely to swallow them and become impacted.

Reptile carpets, on the other hand, are much safer for young dragons and are suitable for adults, too. They can also be cut to size and used for almost any type of tank. The only downside of reptile mats is that claws can get caught in them; however, you can trim your dragon’s nails every few weeks to avoid this issue.

Ease of Cleaning

This is a matter of personal preference, and it comes down to how much time and energy you are willing to spend on cleaning your beardie’s tank. For the most part, reptile carpets are easier to clean and can be washed with tap water before being left to dry and returned to the tank.

When it comes to loose bedding, you’ll need to scoop and remove solid waste regularly to prevent odors from building up. Also, depending on how many reptiles you have and the type of substrate you are using, you’ll also need to remove and replace everything every couple of months to keep the tank clean.


Bearded dragons originate from the arid deserts of Australia, and they are used to humidity levels between 20-40%. Anything above 50% is too high and unsuitable for a bearded dragon to live in, as too much humidity can cause respiratory issues.

Keep this in mind when choosing a substrate for your bearded pet, and pick bedding that will help you control humidity levels within the enclosure.

Replacing the Substrate

Think about how often you want to replace the entire substrate. The more often you have to replace it, the more money you’ll spend in the long run. This, however, holds true only for loose substrates, since reptile mats are washable and can be reused countless times before they have to be replaced.

Odor Control

Last, but definitely not least important, is odor control. Odor buildup can be a problem with many substrates, so if you don’t want to deal with unpleasant smells from your dragon’s tank, this is an important feature to consider. Some types of substrates are treated with biodegradable enzymes that reduce odors, so consider those for more effective odor control.


There are regular expenses involved in taking care of a beardie, and among them is substrate. Price differences may seem miniscule but this adds up when you consider that you’ll have to provide this for the duration of your scaly friend’s lifetime.

FAQs About Bearded Dragon Substrates

What is the best thing to put in the bottom of a bearded dragon tank?

Reptile carpet is generally the best type of substrate to use for a bearded dragon tank regardless of your pet’s age. Unlike loose substrates, reptile carpets can’t be accidentally ingested and cause impaction, which is a potentially life-threatening condition for beardies.

What is the best reptile substrate?

Ultimately, your beardie’s age will determine what is the best type of substrate for them. Loose substrate is a good choice for adult bearded dragons since it recreates their natural habitat and allows them to dig and burrow. When it comes to juvenile beardies, reptile carpets are a much safer and better option since they can’t be accidentally ingested.

Is coconut substrate good for bearded dragons?

Coconut fiber is a good substrate for adult bearded dragons. It is highly absorbent, easy to clean, and helps create a natural-looking environment. Coconut fiber also maintains humidity easily and supports digging and burrowing.

Is sand good bedding for bearded dragons?

Although commonly used as a bearded dragon substrate, sand isn’t a particularly good choice, especially for juvenile bearded dragons. If accidentally ingested, sand can cause intestinal impaction that might even prove fatal if not treated in time.

It’s best to avoid keeping young bearded dragons on sand or any other type of loose substrate, and you should avoid sand altogether regardless of your dragon’s age, as it clumps and causes impaction particularly easily. Plus, it won’t be easily passed by your beardie’s digestive tract like some other, safer, and more biodegradable loose substrates.

What Is the Best Bedding for Bearded Dragons?

There are many different types of bedding for bearded dragons. Some of them are good, but others are downright dangerous. The safety of your pet reptile should be your number one concern when choosing a substrate for their enclosure.

Keeping safety in mind, I found that the Zoo Med Eco Earth Compressed Coconut Fiber is the overall best substrate for bearded dragons. It’s completely natural, non-toxic, and it allows your beardie to dig and burrow.

Since it’s made from compacted coconut fiber, this substrate naturally absorbs waste and odor, thus keeping the enclosure clean and odorless.
